摘　　要：目的了解安徽省不同人群甲型H1N1流感抗体水平,为防控措施的制定提供依据。方法 2010年1月10～25日期间,采取分层随机抽样的方法抽取4 567名调查对象,进行问卷调查,并运用血清抗凝实验方法检测甲型H1N1流感抗体水平。结果全人群抗体阳性率为29.41%,未接种疫苗人群抗体阳性率为23.94%;全人群中,省会城市抗体阳性率高于中小城市,中小城市高于农村;在全人群和未接种疫苗的人群中,6～岁和16～岁年龄组抗体阳性率较高,60岁及以上组抗体阳性率最低,中小学生抗体阳性率最高,其次是幼托儿童和医护人员。结论人群中甲型H1N1流感免疫屏障尚未建立,目前仍需加强疫苗接种和疫情监测。Objective To explore influenza A（H1N1） virus antibody titres of different people in Anhui,China and set up a basis for control and prevention measures of influenza A（H1N1）.Methods 4 567 subjects were chosen by stratified random sampling from Jan 10th to 25th,2010.They were investigated by an uniform questionnaire and their blood samples were tested A（H1N1） influenza antibody by serum agglutination test.Results Positive rate of antibody for the total people and the people without H1N1 vaccine injection was 29.41% and 23.94% respectively.Of total people,positive rate of antibody in capital cities was higher than that in small or middle scale cities,that in small or middle scale cities was higher than countryside.Of total people and people without being injected influenza A（H1N1） vaccine,positive rate of antibody of the age group from 6 to 15 and from 16 to 24 was the highest,that of the age group more than sixty was the lowest;positive rate of antibody in students in middle and primary schools was the highest,followed by children in the kindergarten and medical workers.Conclusions Immunologic barrier for controlling the spread of influenza A（H1N1） hasn＇t been established,so we still need to advocate the disease control measures,such as vaccine injection and disease surveillance.
